Application filed May 8, 1895. Serial No. 548,565. (No model.) Patentedin Germany February 6, 1894:, No. 78,217, and in Austria-Hungary June26, 1894,110. 1,329 and No. 22,736.

To all whom it 11mg concern:

Be it known that I, CHRISTIAN SE'YBOLD, a subject of the Emperor ofGermany, and a resident at Zweibriicken, in the Kingdom of Bavaria,Germany, have invented new and useful Improvements in Looms, (for whichI have obtained Letters Patent in Germany, No. 78,217, dated February 6,1891, and in Austria-Hungary, No. 1,329 and No. 22,736, dated June 26,1894,) of which the following is a specification.

My invention refers to improvements in letoff and take-up movementsfor.looms, the

nature of which will be fully explained in the following specification,in connection with the annexed drawings, in which- Figure 1 represents aside elevation, partly in section, on the line 1 1, Fig. 2, of part of aloom provided with my improvements. Fig. 2 is a sectional plan of thelet-off and take-up movements, the section being taken on the line 2 2,Fig. 1. Fig. 3 is a similar sectional plan of a modification.

Similar letters of reference designate corresponding parts throughoutthe several views of the drawings.

Referring now to Figs' 1 and 2 of the drawings, the letter T designatesone of the side frames of a loom; M, the warp-beam; N, the cloth-beam,and A the lay or lathe.

L is a shaft mounted in the frame T and carrying at its inner end abevel-gear '6, engaging a bevel-gear 7.: on a shaft .2, Fig. 2, theopposite end of which carries a worm 9, engaging a worm wheel q, placedon the shaft of the warp-beam M between the frame and the end of thewarp-beam M. Upon the outer end of the shaft L is mounted a pinion g,and between the latter and the frame is placed a ratchet-wheel r.

a is another shaft mounted in the frame and carrying at its inner end apinion m, engaging a gear-wheel a, mounted between the frame and thecloth-beam and upon the shaft of the latter. Upon the outer end of theshaft a is loosely mounted an internally-toothed wheel f, into which thepinion g on shaft L meshes. Fixed upon the shaft a is a gearthe innerteeth of the wheel f and the teeth of the fixed wheel b.

\V is a weight suspended 011 a rope or chain 5, passing over a pulley oand attached to the wheel 0.

Bis an arm projecting from the lay and connected to apawl-oarryin g armH by means of a rod 0, bell-crank lever D, rod E, lever F, and rod G,whereby motion is imparted to the ratchet-wheel r from the lay.

The operation of the above-described apparatus is as follows: During theforward motion ofthe lay the arm 13 is depressed, the rod E pushedtoward the right, and the rod G, with the pawl-arm H, to the left, thepawl sliding over the teeth. During the return motion the ratchet-wheelr is turned a certain distance, and with it the pinion g, as well as thebevel-wheel 1', which latter, through bevelwheel 7t, worm p, andworm-wheel q, turns the warp-beam a certain amount, letting off the warpcorrespondingly. The pinion g, under the action of the ratchet-wheel, isturned to the right, and under the action of the weight 1V to the left,and is then free to adjust its position; but under the action of theweight it will transmit a uniform moment of force to the cloth-beam;that is to say, the force will be constant for a given radius. 13yproperly proportioning the parts, and in particular the wheels 15 and 7cof the let-01f, the weight WV need not be wound up in weaving ordinarylengths of goods. Assuming the rope-wheel with the axis cl of theplanet-wheel e to remain stationary during a forward movement of theratchet-wheel, the cloth-beam would be moved forward a fixed amount, butif this should cause too much strain the weight V will yield and reducethe motion of the cloth-beam.

Fig. 3 shows, on a larger scale, a modification of the apparatus shownin Figs. 1 and 2. In this figure r is the ratchet-wheel, the shaft ofwhich carries a pinion g, meshing into the outer teeth of a gear-wheelf, loosely mounted upon a shaft a. This gear-wheel f" has a beveltoothed rim, and a similar bevel-wheel b is mounted on the same shaft a.Between the two bevel-wheels is placed to mesh with the same abevel-pinion e, mounted on the rope-wheel c.

The operation of this apparatus is substantially the same as that of theapparatus shown in Figs. 1 and 2.

hat I claim as new is 1. In a combined let-off and take-up for looms,the combination with the warp-beam, the cloth-beam and the lay, of aratchet-wheel, an operative connection between the lay and saidratchet-wheel, means for transmitting motion from the ratchet-wheel tothe warpbeam, a pulley, means for subjecting the same to a constantturning stress, a planet-wheel carried by said pulley, and two toothedwheels meshing with the planetwvheel; a shaft; one of said wheels beingfixed upon said shaft and geared to the cloth-beam, and the other wheelbeing loose on the same shaft and geared to the ratchet-wheel,substantially as and for the purpose set forth.

2. In a combined let-off and take-up for looms, the combination with thewarp-beam M, the lay, and the cloth-beam N, of a ropepulley c, a rope s,a weight V connected by said rope with said pulley, a ratchet-wheel 0,an operative connection between the lay and said ratchet-wheel, meansfor transmitting motion from the ratchet-wheel to the warpbeam, a shaftto geared to the cloth-beam, a toothed wheel f geared to theratchet-wheel shaft and loosely mounted on said shaft a, a toothed wheelZ) fixed to the shaft a, and a planet-wheel 6 carried by the rope-pulleyc and meshing into the wheels I) and f, substantially as and for thepurpose specified.

3. In a combined let-off and take-up for looms, the combination with thewarp-beam, the cloth-beam and the lay, of a ratchetwheel, an operativeconnection between the lay and said ratchet-wheel, a wheel g on theWarp-beam shaft between the end of the warpbeam and the frame, anoperative connection between said wheel and the ratchet-wheel, arope-pulley, a rope, a weight connected by said rope with said pulleyand tending to turn the same, a planet-wheel carried by said pulley, ashaft a, two toothed Wheels meshing with said planet-wheel, one of thesaid wheels being loose upon the shaft a and geared to theratchet-wheel, and the other being fixed upon the same shaft a; atoothed wheel a fixed upon the cloth-beam shaft between the clothbeamand frame, and a pinion m fixed on the shaft a and meshing with thewheel a, substantially as and for the purpose specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
